The invention has for its object the provision of a novel and improvedtype of wringer employ- 5 ing a pneumatic roll in co-operation with aroll so grooved as to tend to distribute equally between the rolls afabric material fed therethrough. The invention consists also in the provision of n ovel means'for mounting and inflat- [0 ing the pneumaticroll and for renewing the roll surface and for carrying off the watersqueezed by the rolls from the material therethrough.

In the drawing: i F'igure l is a view partially in front elevation andpartially in section showing a wringer device embodying the invention.

Figure 2 is a view on an enlarged scale showing in detail a fragmentaryend elevation of my improved device, the trough being partially brokenaway to a section exposing the bearing block for the yielding roll.

Figure 3 is a fragmentary detail view on an enlarged scale showingprincipally in section, the

associated ends of the respective rolls. portions of the rolls beingillustrated in elevation.

- Figure 4is a fragmentary detail view showing a replaceable cover ortread for the pneumatic roll.

Like parts are identied by the same reference -characters throughout theseveral views.

As a part of my improved wringer support I provide a tubular standard at5 having supporting legs 5 which are preferably adjustable as clearlyillustrated in Fig. l, and which preferably provide space within which apail 1 is receivable beneath the tubular standard 5 to receive waterexpressed by the wringer. The standard may be provided with bracket armsI4 to support other Peil-S At its top the standard I carries a trough 3which drains through the standard 5 to the pail 1 and serves as a partof the wringer frame. 'Ihe trough I has a rigid sleeve 3 projecting intothe standard to serve as a fulcrum upon which the wringer may be swungbodily about the standard.

At each end of the trough 8 there are U-shaped guide members Il and Ilrespectively, the latter having a circular loop I2 formed in its upperso end of suillcient diameter to pass the pneumatic roll hereinafter tobe described, to facilitate the assembly and'disassembly of the parts.

Slidable in the respective guides Il and Il are the bearing blocks I5and i5 carrying the trun- II nion shaft l1 of the lower roll I3. Thisrollmay comprise a tube, preferably metallic, carried by a spider I3 atits end from the trunnion shaft i1. The tube has its periphery providedwith intersecting helical grooves 20 and 2i of opposite pitch, whichserve toieed the material axially of the 5 rolls in the course of itsprogress therethrough and to distribute the material between the rolls.At each point of intersection of the grooves 20 and 2l, and elsewhere ifdesired, there are holes 22 which open through the tubular roll I8 tothe 10 K interior thereof to carry away water which may have beenexpressed from the material passing between the rolls and may beconfined on the surface without opportunity of escape. The grooves andholes together provide,means for preventing 15 any such water fromaccumulating.

The bearing blocks 23 and 24 are removably restrained by bolts 25 and 26from yielding upwardly in the guides III and il. The shaft 21 whichextends through these bearing blocks is 20 tubular and'is formed at 23to provide a crank having a pump barrel 29 as a handle. The usualplunger 30 is mounted in the pump barrel and reciprocable therein toforce air under pressure through the tubular crank 23 and shaft 21. For25 emergencies the other end of the tubular shaft 21 may be providedwith a conventional valve stem 3l and cap 32 for connection of anordinary tire pump to produce the required pressure. When the bolts 25and 26 are withdrawn the bearing 30 blocks 23 and 24 may be raisedtoward the top of their, respective guides III and i I, and the shaft 21may be withdrawn from the bearing block 23. 'I'he block 24 and thewringer roll assembly on shaft 21 is bodily witndrawabie through theloop 35 Shaft`21 carries at each end a pair of heads such as those shownin Fig. 3. The inner head 33 provides the roll hub and is pinned toshaft 21. Screwed thereto is the clamping outer head 34 which holds theend of the tube 35 of rubber or the like, which comprises the pneumaticroll. I preferably employ an inner solid roll at 36 which prevents thepneumatic tube 35 from being 45 unduly collapsed. There are ducts 31aioiding communication from the interior of the hollow shaft 21 throughthe solid roll 36 to the interior of the tube 35, whereby the innersurface of the tube may be subjected to air pressure.

If the tube 35 becomes worn it may be replaced readily by loosening theclamping members 34 and removing the upper roll as above described. Itmay, however, also be covered by a supplemental tube 34 drawn over thetube 35 as shown 55 in Fig. 4 to provide a new surface with the metallicroll Il.,

It is to be noted that the compression springs 39 act upwardly on thetrunnion blocks I5 and I6 of the lower roll only. The upper blocks 23and 24 are held stationary against the bolts 25 and 26, and the yieldingof the upper roll surface is and to co-act fentirely pneumatic.

tribute the material to avoid unequal thickness and at the same timethey serve to carry off expressed water from the bite of the rolls,either allowing such water to run about roll IB to a point where it canfall by gravity into trough 8, or allowing such water to pass throughthe holes 22 to the interior of the roll I8 and through the open endthereof into trough 8. In either case the water is discharged throughthe rotatable sleeve 9 into the tubular column 5 and thence to the pail1.

I claim:

1. In a Wringer roll, the combination with supporting means,` of a solidinner roll carried by said means, a iiexible tubular sleeve carried bysaid means in sufficiently closely spaced relation to said inner roll tocomprise an auxiliary support for said sleeve eiective following amoderate distortion thereon, a supporting shaft extending through saidinner roll, and means for infiating the space between said inner rolland sleeve.

2. In a wringer roll, the combination with a supporting shaft, of aninner mounted head, a flexible tubular sleeve having its end engagedover said head, a cup-shaped clamping outer head holding the end of saidsleeve in clamped engagement with said inner head, and means connectingsaid heads and adjustable axially of said shaft for applying clampingpressure to said sleeve.

3. In a wringer, the combination with a solid cylindrical support, of aflexible tubular sleeve suiiiciently larger in diameter than the supportto be normally out of contact therewith except when distorted underpressure, said sleeve being mounted over said support in suflicientlyclosely spaced relation to receive auxiliary support therefrom upondistortion of said sleeve, means hermetically connecting said sleevewith said support, means for inflating said sleeve, means mounting saidsupport for rotation with said sleeve, a eoacting roll with which saidsleeve is engageable, and a frame in which said coacting roll andmounting means are disposed in operative relation.

5. `In a wringer, the combination with a rotatable support comprising aninner head, of a exible tubular sleeve having its end engaged over theperiphery of the head, a cup-shaped clamping member having a faceclosely adjacent the end of said head and having a peripheral wallengaged over the end of said sleeve for holding said sleeve to saidhead, and screw threaded means connecting the face of said cup-shapedclamping member to the end of said head for maintaining the endY of saidsleeve under clamping pressure.
